ford 3600 leaking antifreeze

rking · Apr 10, 2018

I was going to use the post hole digger on my tractor for pen repair and I saw the radiator needed fluid. I added about 1 gallon of water/antifreeze solution. When I started the tractor, I noticed a small amount of spray but nothing major. I dug my two holes but on the second one the leak had gotten much worse. I quickly returned to the barn. I placed a bucket under the tractor to collect the antifreeze.

I had thought that one of the radiator hoses had a hole but when I examined it today, it appears to be leaking from the radiator fan shaft. I added more water to the radiator and have a slow drip from that shaft. I haven't started the tractor and don't know if I will be able to see anything since the antifreeze is hitting the fan and spraying everywhere.

Any suggestions of what is wrong?

Grasp the fan/shaft and see if it wiggles. Sounds like it will and you need to replace the water pump. But, never assume, see what kind of play it has. If not keep looking.

A water pump seal can leak even if the bearing is still tight. Judging from the pic, it sure looks like the water is coming out of the weep home, loose fan or not.

Weep Hole I bet,
I just replaced one on a friend of mines 3000 Ford. Same exact leak drip down location

I do not know how old that antifreeze is, but I would replace it and make sure anti cavitaiton is up to snuff when replacing water pump.

I went back out to the tractor to check the fan blade/shaft for wiggle and there was definite "wiggle". A couple of questions to get "old
blue" back to working order. Is changing the water pump a job for a novice mechanic? Is it a matter of simply taking apart with wrenches.
And, what the heck is a weephole there. Any more guidance is appreciated. This tractor has sat all winter with the shredder attached. I
had some cow work a few weeks ago and realized that the post holding the gates have rotted and needed replacing. I got the post hole digger
on this tractor and really hate to take it off again. I got one wing done yesterday in the misting rain and was going to continue to the
other side. Guess it is always something!

Changing the water pump is easy. No sure about the 3600 but I assume it is the 3000? Pull the front hood then power wash and CLEAN the front of the motor. Drain the radiator, then pull the hoses then the radiator. Loosen up the belt and at that point you should see what bolts hold the water pump on. I would use a square tube with 100 grit sandpaper wrapped around it and clean the block where the new water pump will go keeping the square tube flush and level while lightly sanding. Pull the fan off the front of the old pump. With the block and new pump clean run a small amount of RTV around the pump then put on the gasket and install the pump. Torque the bolts to spec.
That should about do it.

Dont forget to add water and antifreeze!!

Absolutely, either way they can leak. I see there's photos up now, none were up when I responded earlier.

And, what the heck is a weephole there.

The weep hole is just to give the coolant someplace to go if it does leak around the shaft rather than building up inside the housing and rusting things.

Bern · Apr 11, 2018

Theoretically, the weep hole keeps the water out of the bearing, which theoretically keeps the bearing from going out and causing the fan to
wipe out the radiator. It's also there to indicate to the owner that the seal is in fact leaking so that the issue can be dealt with before
it gets worse.

If you pull the lower radiator hose off, you can get your hand in, and remove the 4 fan blade bolts... and just drop the fan down in the shroud housing... then you can remove the front half of the water pump and replace it.... pretty cramped and scrapped hands, but I have done it many times... If you cut a 2" notch in the fan shroud, you can pull the fan blade out and bend the notch back in when done. That gives you lots of room.

Thanks!

When you remove the PHD, support it in the upright position with a chain thrown over a substantial tree limb. Makes it easier to mount/dismount and keeps the implement off the ground.

rking · Apr 13, 2018

I have been thinking about doing this. I chain it to a post under the barn but it is always "trouble" to hook back up. Do you protect from the weather?

Dollar Bill · Apr 14, 2018

Do you protect from the weather?

Rain won't hurt it but yes, I usually tarp any implements that I don't store in the barn. Ensure it has enough air flow to prevent condensation.

I think I am going to try this. Thanks

I went to the parts section of Yesterday's tractor to order the water pump for a 3600 and I found 3 different water pumps listed for this tractor. Do I need to find a number on my engine to determine which one to order? I don't want to have to take the pump off to see which one it matches.

I ordered the first one in the photo below.. the "for tractor models 345 C" and it fit perfectly.
I have had pretty good luck with Yesterdays Tractors and stuff fitting.
I would give them a call and make sure what tractor you have and what works.

That is the one I placed in my cart. I haven't ordered yet. Thanks

1st pump is the complete pump with back housing and what I normally get.
2nd pump has dual grove pullet normally used on cab tractors with AC
3rd pump is same as first but no back housing.

I just did my 2600. It's a little bit of work but not bad. I pulled the frt. cap and the radiator, from there it's a breeze. I replaced the thermostat and hoses while there. After all they were 41 years old.
On the post hole digger you can run it in a soft spot a little and disconnect and it will stand there waiting for you.
